It is possible to get to 2400 mhz and above in SB, but the catch is it is extremely rare to find a SB CPU with a good enough IMC to do so.

Huh? My memory settings are limited at 2133 MHz. It won't physically allow me to go any higher ...

They don't need heatsinks so long as you have decent case air flow.
For now they get direct acces to fresh cool air, but when my rig is done they will feel the wrath of the radiators >.>

Yeah, you only get higher clocks upping bclk, which is HARD without ln2 or dry ice.

Oh. I see ... thnx for the info

Also, any ideas on how to force a constant voltage? With both offset and fixed, my load voltage fluctuates between 1.432-1.448. It's set at 1.395 in the BIOS. LLC is broken anyhow, I'll have to double-check if that ever stuck

PPL was enabled
Spread spectrum is enabled

And i'll give you guys more info later when I'm home

Hmmm, not familiar with your motherboard's bios settings/features, so I doubt I can be of help.
Sounds like you got a too high value for LLC and it might make your vcore overshoot. You should have 0 llc for offsets and llc enabled for fixed vcore. With 0 llc in offset mode your idle vcore will be low but not too low as to cause instability and your load vcore will droop a bit, but if you have a high enough offset you can compensate it.

So I can't get my sticks to boot at 2133 no matter what voltage I put them. I've loosened timings and jacked up the volts but it'll always hang. Only volts I've messed with are offset, additional turbo voltage and dram voltage

Keep us posted on your luck with that board. I'm looking at it or the P8Z77-I for a sff scratch build I'm going to tackle later this year, the ASUS fits my color scheme better, but I have an affinity for ASRock boards for the OC granularity. If all goes as planned I will probably take 8 gigs of my miracle ram and throw it in that box, and leave my sig rig with the remaining 8.

What timings are you using?

Use the stock xmp/auto timings first and make sure they match the sticker. That should work for 2133mhz really, try 1.65v for dram and 1.2v for both vccio and vccsa.

@ivanalibire

To be sure that everything is maxed out, I tried vcore=auto (manual at 45x multiplier), vccio=1.2v, vdimm=1.7v and set ram to 2133 11-11-11-30-2t. I was expecting for it to pass hci memtest without any errors because of this super relaxed timings. I run memtest overnight and when I woke up there isn't any error. It was at around 1400% coverage already and then after a few seconds I got an error?

What's up with this? Should I increase vcore to 1.4v first to eliminate the possible need of increased vcore during ram stability testing?

To completely isolate the cpu you should run stock clocks and auto vcore and focus on the ram itself first.
You ran memtest86+ or hci memtest overnight? regular memtest86+ doesn't work for stability once oced, only to check for errors at stock clocks.
